Very true. But not adapting to the world as it is is a personal choice. So, yes, while perhaps exclusionary, it is self-exclusionary. Everyone should have the right to self-exclude from anything they want. But the world is how you find it, not how you wish it to be, and we all have to deal with the consequences of our choices. Even when our choice is to bury our heads in the sand and pretend that nothing has changed and that we don't need to adapt.
